Hello everyone I'm feeling kind of proud that I've updated most of my stories recently, so here is Knowing Leo to continue that update streak.

Connwaer Heap : Nope, everyone must be miserable ;) I'm glad that you think my writing is realistic; I would hate to write something that could never, ever happen. And I'm not sure on Nico's exact birthdate, but I think that he was born sometime in the early 1930s, so I think it is possible that he saw at least the first year of the war.

Kris Awesomeness : Nico might tell him, he wants to help Six in any way possible so that would make sense. And everything I write seems to have yaoi undertones whether I'm aiming for that or not. I'll give you the rusty spoon if you need one, and I'll help you hold her down if you want?

Melancholy's Sunshine : Yep, things are going pretty crazy. About Six's instinct to run away, I feel that maybe even before his mother's death this could have been an issue. Some children always to choose the flight option instead of the fight option. Maybe it wouldn't have been to such an extent when he was younger, but he could still run away when things get tough, like if he had an argument with his mum for instance. However, the impact of some memories may have bled through; you'll just have to see as the story develops.

Guest : Ah, thank you. I hate making silly mistakes like that, so thanks for pointing it out so I can remember it for next time.

Beautiful Blobby : Thank you, I hope that you enjoy the rest of the fanfiction.

Lyra : I can understand the bobby pin and the rusty nail, but what are you going to do with the pizza and the penny? Hide the penny inside the pizza so I choke? Poison the pizza? If so, can I have a chicken and sweetcorn pizza if it's going to kill me?

Zoethezany III : Yeah, why not? I'm happy that my plot twist got you, it's fun to shock people

Skyfir3S4kur4 : Teehee, I can hear the screaming from here. And I do it because I have no other choice, I must write angst. It's in my blood. I'm glad that you think that the chapter was good, and there is an explanation for Fifteen's behaviour in this chapter.

Neon Wish Likes Pine Trees : Meow meow.

Sidda : I really want to watch Hetalia but I never have the time and I have a load of other animes to finish first. And I have read Magnus, Hearthstone is just my precious child. Have you read it? I'll listen to that song; I love songs that give you feels.

RedRaven05 : Whoo, I'm glad that I didn't disappoint. And that was probably one of the worst ways that Six could have found out about his mother. Nico and Hazel really have their work cut out for them getting him back safely.

Disclaimer : Was there a de-aged Leo in the actual books? No? Well it wasn't my work then.


Jason's P.O.V

Jason hated the fact that he couldn't help rescue Six, but he and Piper had their own Leo to deal with.

And Jason had a niggling doubt that Fifteen's behaviour may have a more insidious reason than him just being fed up with the situation.

As they headed back to the training room (leaving the others behind to try and cheer up Eight) Jason grabbed Piper's wrist gently to halt her for a moment.

She gave him a quizzical glance.

"Enyo is the Goddess of strife, right?" Piper's eyes widened in horrified understanding.

"Oh Gods!" Her pace increased, and Jason quickened his own steps, overtaking his girlfriend as the true implications of Enyo's possible influence rampaged obnoxiously through his head.

He flung the door open, half expecting Fifteen to still be pacing around like his animal namesake, or at the very least beating the stuffing out of one of the training dummies. Possibly with the training room burning to cinders around him.

What he didn't expect to see was Fifteen sitting on his heels and hunched over, hands clasped over his ears.

Piper pushed him into the room lightly. He heard her quick intake of breath as she observed the distraught image in front of them.

"Oh, Fifteen." She breathed. The Latino's hands pressed even harder against his ears, then he seemed to change his mind and looped his arms over his head instead. Jason took a cautious step towards him, but was stopped in his tracks when Fifteen threw up a hand and a trail of flame snaked out in front of him.

"Don't." His voice was rough, hoarse as if he had been crying or, screaming.

"Fifteen, we think that we know what's going on. Enyo is influencing you." The boy's trembling arms dropped to his sides, and he rose slowly from his position on the ground.

"Really? I'm being influenced? Has it not occurred to you that I might actually be legitimately angry?" Jason once again tried to move towards the younger demigod, but this time the flame snake curled around his body, not quite touching the skin but close enough that he couldn't move without singing the hair off his arms which were now pinned to his side.

"Fifteen, don't you think that it's weird for you to go from acting pretty reasonably to lashing out in a matter of minutes?" Piper's voice was soft, though her eyes darted between the flaming circle of death that was looped around Jason's body to the son of Hephaestus who had put it there.

"Yeah, it's not like I have a reason or anything. Six has been kidnapped, and what do you think the goddess of strife is going to do to him?" Jason froze.

"What do you think she's going to do to him?" Leo barked out a laugh, full of venom.

"She's going to tell him about mom!" Jason's guts twisted unpleasantly and he was almost overcome with nausea.

"W-what?" He managed to choke out. Fifteen drifted over to one of the training dummies. Then his fist lashed out, flames following his fingers to leave a smoking hole in the middle of the dummy's chest.

"What better way to cause strife on-board the Argo at the moment then by setting the Leo's against each other. She's targeting Six because he'll be easy to make angry." The flames around Jason seemed to be burning hotter as Fifteen's rage rose, and he shifted uncomfortably as the ring of heat around him intensified.

"And she's targeting you because you are the most responsible Leo." As soon as Piper said this, the ring of flames constricted slightly, and Jason let out a startled yelp as the flames licked at him. He wasn't burning properly, but his arms were starting to go red.

"Fifteen!" Piper yelled, and Fifteen's eyes turned towards him, almost lazily.

"Move anymore Jason, and you'll be toast." The pun was tossed out lazily, and Jason witnessed the annoyance creep onto Piper's face.

"Fifteen, will you just let him go?" Despite her irritation, Jason could tell that Piper had refrained from using charmspeak.

Their usually impish young friend sighed dramatically and waved a hand in the air (probably more for effect than a need of the motion) causing the flames to disperse.

Jason glanced down at his arms, noting that although they were quite red, he hadn't been burnt in a single place.

"¡Nadamas déjame en paz! (Just leave me alone!)" The tanned demigod turned around and walked over to the dummy that he had punched previously. He clicked his fingers, and flames sprang up all over the straw creation. Jason wasn't sure of what Fifteen had said, but he got the message that Fifteen was feeling very friendly right now.

Jason watched, stunned, as the face of the dummy smouldered. It looked like some creature straight out of Tartarus. And as the flames climbed, Jason swore that he could see a beautiful woman smiling cruelly. Her eyes locked onto his and her grin widened before she winked and disappeared.

If Jason had had any doubts that Enyo was behind all of this then they were erased by actually seeing her evil smile in Fifteen's fire.

"Please listen to us." Piper came to stand by Jason's side, sliding her hand into his.

Fifteen stood motionless, back to the couple, bathed in the glow from the flaming dummy.

"Why should I? Why should I listen to you? Yo soy la tercer parte que no es necesario. (I am the unneeded third part.) You don't really care about me. I'm just an inconvenience, that annoying friend that you have to put up with." Jason's heart clenched. He'd forgotten that Leo had ever felt this way as they had resolved it after watching his memories. But this Leo hadn't been there for that, and he therefore had all of the same issues that Leo had possessed in the past.

"You aren't an inconvenience, Fifteen." Fifteen span around, and Jason actually took a step back, alarmed at the glowing red eyes currently replacing the normal chocolate orbs. What alarmed Jason the most wasn't even the fact that Fifteen's eyes were red; it was the shade that scared him. Occasionally when Leo got really emotional, or was really concentrating on his powers, his eyes would get a warm reddish tint that was only visible in certain lights and at certain angles. This red was pure scarlet, the colour of spilled blood. Enyo's influence was physically manifesting.

"Cállate! (Shut up!)" Fifteen's chest was heaving, and black smoke formed a demonic parody of a halo around his messy curls as small flames flickered into existence.

"You don't need to pander to me like I'm one of the little brats. I'm old enough to understand that you just pity me. I want you to stop. Stop pretending to be friends with me."

"We aren't pretending!" Piper almost wailed this statement. Jason pulled her closer, hoping to comfort her with their close contact.

Bad move. Fifteen's eyes zeroed in on their linked hands. He sneered.

"Sorry lovebirds, why don't you take your PDA elsewhere? I sure as hell don't want to see it."

"You say that you aren't one of the little brats, but your behaviour sure contradicts that." Jason looked to the doorway in confusion.

Annabeth and Percy were standing together, eyes analysing the scene swiftly, almost as if they were preparing to go into battle.

"Weren't you two with Eight." The oldest demigods strode into the room. Fifteen's eyes darted between the two couples warily before his face shifted into an angry snarl.

"Frank and Coach Hedge are taking care of him. So what's going on here?"

"Great, two more dummies have joined us." Jason's eyes snapped over to his older friends to see how they would react to this. Percy grinned slightly, but the expression was tempered by the worry in his eyes. Annabeth frowned, and then sized Fifteen up.

"So Fifteen is under Enyo's influence." She summarised a horrific occurrence into one concise sentence, Jason would have been impressed if he wasn't trying to gauge how far gone Fifteen was.

The scarlet eyes twinkled.

"Let's see just how many dummies I can set on fire."

Hazel's P.O.V

The awful video continued playing in the background as Six glared up at Fourteen, eyes filled with a maelstrom of dark emotions.

"Six, we wanted to protect you." Fourteen reached out for his younger counterpart yet Six dodged once again.

"Don't touch me, monstruo!" The child yelped as he scrambled away. Fourteen's face was at first hurt, but then it changed. Fourteen now appeared devoid of all emotion.

"Six, no version of you is a monster." The child's frantic eyes turned towards her, and the daughter of Pluto shuddered at the desolation in them.

"Nosotros la matamos, es completamente nuestra culpa. (We killed her, it's completely our fault.)" The Spanish words held a frightening depth of emotion, but Hazel wasn't certain on their meaning.

Fourteen was shaking, head down.

"I should leave." Before Hazel could say a word in protest, Fourteen bolted out of the door.

Hazel looked over at her sibling.

"Hazel, would you go after him please?" Hazel hadn't expected that, Nico and Fourteen had seemed to get closer, and Hazel had just assumed that Nico would want to go after him and leave the child to her.

"Are you sure?" She didn't know why she was so doubtful, she had gotten closer to Fourteen as well, but she couldn't figure out why Nico would choose to comfort a child rather than the teenager that he knew how to deal with.

Though, even with these reservations, Hazel was going to trust her older sibling.

"Okay. Take care of him." Nico nodded, and Hazel darted out after the errant teen Leo.

She found him hunched over further down the corridor his breathing was erratic, but thankfully he seemed to be restraining his panic and not on the verge of a panic attack.

Sliding down to the ground in front of him, Hazel did her best not to hover too much.

"Do you want to talk?" Fourteen shook his head. They remained sitting like that for a few minutes, before Fourteen sighed shakily and hauled himself up.

He offered her a hand, and Hazel graciously accepted it.

"Let's just focus on getting Sic back to the ship." Hazel agreed, but when they got back she was definitely going to try and help Fourteen.

They got back to the room with Nico and Six.

The child was enveloped in her older brother's arms, and as she got closer Hazel could hear that Nico was telling Six about how his mother and sister had died.

The little boy was still crying heavily, though he appeared to be comfortable being hugged by Nico.

"Bravo, little demigods, you've done such a great job of looking after your de-aged friend." The sarcasm buzzed in her ear, grating against her emotions. Irrational anger filled her, and she felt an ugly snarl forming on her face.

These Leos had been nothing but trouble since the split, always running off and freaking out on them. Just like regular Leo, they had to make everything difficult.

No! Leo wasn't like that. He tried just as hard as everyone else, maybe even more so.

Hazel reopened her eyes, though she wasn't sure on when exactly she had closed them.

Nico appeared dazed, holding his head with one hand. Fourteen was on fire, and had moved so that he was standing as far away from them as possible.

Six was also covered in flames, and he was staring at them in horror.

"No, no, no, no." He whimpered.

Hazel's eyes were then drawn to the Goddess. Her black hair fell in a waterfall to her waist and her eyes glowed red. Painted red lips twisted into a monstrous parody of a smile.

"Hello darlings." She simpered in a sickeningly sweet voice. Then, all pretence of friendliness dropped from her lovely face. Hazel drew her weapon in sync with her brother. The Goddess laughed. The sound in itself was like an attack, and Hazel could feel a frenzy working up inside of her. She clamped it down, tightly.

"Oh yes, please unsheathe your weapons. You're going to need to defend yourself very soon." She laughed again before disappearing. Hazel glanced over at Nico in surprise. Why would they need to defend themselves if the Goddess had disappeared?

Hazel's question was answered when Nico's eyes widened. Then her brother launched himself at her, bringing her to the ground painfully as a fireball shot itself over their heads.

They both leapt up and looked at the two Leos. Their eyes were red and filled with an indescribable rage. Fire coated them from head to toe, like a flaming coat of arms.

In each tanned hand, was a fireball.

Hazel gulped.


Well, I think that's a good place to end this chapter I'll see you all soon and I hope that you liked it.
